Frequently Asked Questions
What is the pitch and body length of the Harwin M20-9770746 connector?
The Harwin M20-9770746 features a 0.1 inch (2.54 mm) pitch with a body length of 0.7 inch and body breadth of 0.1 inch, making it compatible with standard 0.1 inch grid PCB layouts. It has 7 positions arranged in a vertical receptacle configuration.
Which PCB assembly environments is M20-9770746 suitable for given its contact finish?
The M20-9770746 uses Tin (Sn) over Nickel (Ni) contact finish on the termination side, providing corrosion resistance suitable for standard soldering processes at temperatures up to 260°C. This makes it appropriate for consumer electronics, industrial automation, and embedded system PCB assemblies requiring reliable long-term electrical connections.
How does M20-9770746 compare to other Harwin M20 series connectors in terms of position count?
The M20-9770746 offers 7 positions within the M20 series, giving designers 7 independent signal or power contacts at 0.1 inch pitch. Alternative M20 variants exist with fewer or more positions (e.g., 2 to 40 pins), allowing designers to select the exact pin count needed for their application without wasting board space or adding unnecessary connectors.
Is the Harwin M20-9770746 compliant with RoHS regulations?
Yes, the M20-9770746 is fully RoHS compliant, meaning it contains no restricted hazardous substances such as lead, mercury, or cadmium. The connector carries a Pbfree code of Yes, ensuring it meets EU Directive 2011/65/EU requirements and is suitable for export to markets with strict environmental regulations, including Europe and Japan.
